Double Iridium Construction The NGage BNL8RTII-9 Spark Plug uses iridium on both the center electrode and the ground electrode. NGage classifies this as Double Iridium construction. Iridium is selected in spark plug manufacturing for its high melting point and resistance to erosion during repeated ignition cycles. In high-compression and fuel-injected engines, electrode durability is required for maintaining consistent spark formation. The double iridium layout is commonly used in tightly controlled combustion systems. NGage does not publish electrode dimensions, gap data, or service interval claims for this part number. The classification here follows NGage’s official product definition.
